I Think my Climate Control Unit is dead

I Think my Climate Control Unit is dead, I have a 95 A4, Just got it 2 weeks ago. Had the Aircon Charged last night, as I was under the impression that was the problem, but it's not.
It always puts out hot air and only out of the top and bottom vents. Also the Air cons Compressor doesnt kick in (so i'm told).
Do you think this is all down to the Climate control unit?
Any help will be greatly appreciated
Cheers

if the compressor is on then there should be an ice symbol at the bottom left.

You can use the onboard diagnostics to check for errors. just press and hold the recirculate and the up arrow together to enter this mode. you should see 01c, then briefly press the recirc button again to get the reading. to move between items in the list use the temp plus and minus buttons.

The Screens are constantly flashing, when I press the Aircon button the ice symbol only stays on for a second, same thing happens when I press the recirc button.
I entered the onboard diagnostics and quickly got baffled /ubbthreads/images/graemlins/crazy.gif

I have had a slightly similar problem with my 95 S6. The ice symbol or AC or compressor would stay on briefly and cut off. Turned out the freon level was low, so I had it recharged. The problem did not go away, finally I discovered that the electric fan was not working half the time causing the AC system to heat up and consequently tell the AC system to kill the AC compressor.

another thing, if the outside temperature is below 5deg C then the compressor will not switch on unless you choose the window defrost switch. However the recirc button should still continue to operate as normal.
